Compound oxidized styrylphosphine [PDF]

open access: yes, 1979
A process is described for preparing flame resistant, nontoxic vinyl polymers which contain phosphazene groups and which do not emit any toxic or corrosive products when they are oxidatively degraded.

Proton MR Spectroscopy of Neural Stem Cells: Does the Proton-NMR Peak at 1.28 ppm Function As a Biomarker for Cell Type or State? [PDF]

open access: yes, 2011
Recently, a peak at 1.28 ppm in proton magnetic resonance spectroscopy (^1H-MRS) of neural stem cells (NSCs) was introduced as a noninterventional biomarker for neurogenesis in vivo. This would be an urgently needed requisite for translational studies in

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Crystal structure of 2-azido-1,3-bis(2,6-diisopropylphenyl)-1,3,2-diazaphospholidine

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2017
The title compound, C26H38N5P, was synthesized by reacting 2-chloro-1,3-bis(2,6-diisopropylphenyl)-1,3,2-diazaphospholidine with sodium azide and a catalytic amount of lithium chloride in tetrahydrofuran.

One Pot Synthesis of Cubic Gauche Polymeric Nitrogen [PDF]

open access: yesarXiv
The long sought cubic gauche polymeric nitrogen (cg-N) consisting of N-N single bonds has been synthesized by a simple route using sodium azide as a precursor at ambient conditions. The recrystallization process was designed to expose crystal faces with low activation energy that facilitates initiating the polymeric reaction at ambient conditions.

High-Pressure Synthesis of a Pentazolate Salt

open access: yes, 2016
The pentazolates, the last all-nitrogen members of the azole series, have been notoriously elusive for the last hundred years despite enormous efforts to make these compounds in either gas or condensed phases.

Going from Inner‐Skinned to Outer‐Skinned Polyelectrolyte Multilayer Based Hollow Fiber Nanofiltration Membranes

open access: yesAdvanced Materials Technologies, Volume 10, Issue 8, April 17, 2025.
New negatively charged hollow fiber support membranes with an inverted porous structure are fabricated. These supports are coated with polyelectrolytes to form an outer‐skinned polyelectrolyte multilayer membrane. The membranes show a 3.8x increase in active membrane surface area compared to conventional inner‐skinned polyelectrolyte multilayer ...

Toxicological and Physiological Effects of DDT on Caenorhabditis elegans

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2016
Toxicity assays were used in this study to test how DDT affects lethality and brood size of Caenorhabditis elegans (C.elegans) by exposing them to various concentrations of this agent.

Bis[μ-1-hexyl-3-(2,3,5,6,8,9,11,12-octahydro-1,4,7,10,13-benzopentaoxacyclopentadecin-15-yl)urea]bis(azidosodium) chloroform disolvate

open access: yesActa Crystallographica Section E, 2012
In the title compound, [Na2(N3)2(C21H34N2O6)2]·2CHCl3, the sodium cation is heptacoordinated by five O atoms of the crown ether unit of the 1-hexyl-3-(2,3,5,6,8,9,11,12-octahydro-1,4,7,10,13-benzopentaoxacyclopentadecin-15-yl)urea (L) ligand ...
